Having already ticked off metal with Marilyn Mason, alternative rock with Beck and electro with Daft Punk, Hedi Slimane has moved towards more soulful ground for the next instalment of Saint Laurent's Music Project.

Who better to represent the rhythm and blues genre than industry legends B.B. King, Chuck Berry and Jerry Lee Lewis? The trio, now aged 88, 86 and 77 respectively, were scouted out by Saint Laurent's creative director, Slimane, on a tour he took this summer of south and Midwest USA.

Shot in situ, rather than Slimane's previous studio portraits of campaign stars Courtney Love and Ariel Pink, B.B. King wears a bespoke version of the Le Smoking suit in Las Vegas. Chuck Berry and Jerry Lee Lewis, meanwhile, are captured in custom-made tuxedos, with Berry choosing to offset his with a cowboy's bolo tie and captain's hat.
